What does TSE58 indicate in a METAR report?

In METAR reports, the "TSE" indicates the presence of a thunderstorm, and the number following it signifies the minute past the hour when the thunderstorm ended. Thus, "TSE58" specifically indicates that the thunderstorms ended at 58 minutes past the hour. This specific notation is utilized to provide precise information regarding the timing of weather phenomena, which is crucial for pilots and meteorologists when assessing current and past weather conditions. The context of the other options involves misunderstandings about how TSE is used, such as misinterpreting the significance of the number or the indication of ongoing weather events.
